Starcraft 2 will go free-to-play later this month

Meanwhile, "the Zerg (a primitive, but ruthless insect-like army) are now on the run as Terran (human) forces pick off their dwindling numbers-but little do the Terrans know that the Zerg are merely playing possum", we wrote of the game's storyline.

The original Wings of Liberty campaign. That means even those who have never played the game will be able to experience it from the start. Several challenge-mode mini-games will also be included, with focused goals created to ease players into the basics of multiplayer strategies.

Players who already owned any version of StarCraft II prior to October 31 will receive a special Eidolon Ghost skin and three portraits commemorating their founder's status in the game when StarCraftII goes free-to-play. Curious what that actually means?

In order to bring more players to StarCraft II's community, Blizzard now offers the entire Wings of Liberty campaign free for all players. You have to log in between November 8 and December 8 to claim that upgrade though.

Players have to keep in mind that they will need to unlock that mode first by gaining 10 "First Wins of the Day" in unranked games or against the computer.

All Co-Op Commanders available up to level 5, no more rotation! You'll be able to tackle these extra challenging missions with your friends right away. Commanders Kerrigan, Raynor and Artanis will be completely free as well but all other commanders will only be free up to level five.

The move to make the game free to play comes after Blizzard previous year partnered with Google to allow the Web giant's DeepMind's artificial intelligence and machine-learning researchers to use Wings of Liberty for research.

If you download Wings of Liberty and want to grab the later expansions, you can buy them individually for $14.99 or together in the Campaign Collection for $39.99 through the online Blizzard Shop.

StarCraft is a big part of BlizzCon, but also present at the annual event are Blizzard's other franchises, such as Warcraft, Hearthstone, and Overwatch.
